Processed ship-based Multibeam Sonar Data (version 2) acquired in the Central Pacific Ocean during the Atlantis expedition AT11-24 (2005)

This data set was acquired with a ship-based SeaBeam 2112 Multibeam Sonar system during Atlantis expedition AT11-24 conducted in 2005 (Chief Scientist: Dr. Robert Vrijenhoek). These data files are of MBSystem format and include Swath Bathymetry, Acoustic Backscatter, and Sidescan data and were processed by the GMRT Team using the open source MB-System multibeam sonar processing software as part of the GMRT Synthesis effort. These data are included in the GMRT Synthesis, version 2.1. Data were acquired as part of the project(s): Gene Flow and Species Diversity in Deep Sea Hydrothermal Vent Communities and Biogeography and community structure in mussel beds at Pacific hydrothermal vents, and funding was provided by NSF grant(s): OCE02-41613 and OCE03-50554.
